James Corden has confessed he is finding the prospect of working with Meryl Streep "terrifying".

The Gavin And Stacey star is about to begin filming the big screen adaptation of the Tony-award winning Broadway musical about a witch, played by Meryl, who conspires to teach important lessons to various characters of popular children's stories including Little Red Riding Hood, Cinderella, Jack And The Beanstalk and Rapunzel.

James revealed: "I'm shooting a film at the moment called Into The Woods with Meryl Streep and Johnny Depp, and we've started rehearsing, which is slightly terrifying.

"I've not met Johnny yet. But most of my scenes are with Meryl Streep and Emily Blunt. It's thrilling, it's brilliant."

The film is being directed by Chicago's Rob Marshall.

James' new sitcom The Wrong Mans, which he co-wrote with Mathew Baynton - is about to begin on BBC Two.

The show is about two hapless office workers inadvertently caught up in a criminal conspiracy, and while the lads admit they were inspired by many of their favourite action films, they are not sure if they would want to make it into a film.

James revealed: "A lot of people since we finished the show have been like 'You could make a movie of this.' And much as we haven't discounted it - then they'd be in the world of film.

"As a film, it's a film that you've seen. This world exists as films, and brilliant films. And the thrill for us was we didn't know if it could exist as six-part half hour comedy."
